PROBLEM TO BE SOLVED: To provide a superior energy-saving propeller utilizing air that is used for wind-power generation.SOLUTION: Three layers of a heat barrier coating also acting as insulation coating and electrical conduction coating are applied to a wind power generation propeller 8, the second layer of electrical conduction coating is electrically energized to melt snow ice adhering to the propeller to make a self-weight of the propeller light to increase the rotation efficiency of the propeller. Alternatively, a coating mixed with protrusions of slightly larger diameter particles is applied to the rear part of the propeller. Further alternatively, some protrusions are bonded directly to the propeller with an adhesive to cause a normal air-peeling location E to be pushed out toward the rear part of the propeller and to elongate a distance where wind contacts with the propeller to increase an air-contact area and to improve a wind power effect to amplify rotating force of the propeller. In addition, a curved fin 10 or a saw-shape fin is fixed to the rear extremity of the propeller to reduce air-blowing sound and also a part of air peeled off from the propeller is applied to the fin to utilize the wind power again.SELECTED DRAWING: Figure 3 |
